If you can start steam without the workaround then you're in. There's not that much difference depending on the games you already owned. Unfortunately SS3: BFE is no longer in the beta - they decided it was ready for release. Mainly it's access to the Limited beta forum.

We didn't decide it out of beta/ready for release yet. :) We just:

1) had to cut down the number of users as we cannot handle the number of incoming new bug reports (many of which are becoming redundant). We are still working on fixing and improving it.
2) wanted to see how many people actually bought it / will buy it on Linux. (Consider it beta-testing the commercial viability. ;) )
